M24, non smoker, no tobacco, Had wisdom tooth impacted on right side got the one removed. This is left side, here also pigmentation is coming up? Is this normal? When washed with water and when i lay my finger over that area it feels granular/rough and also most of the time when upper teeth gets rubbed on the surface of bm, it feels roughy, i am scared if its cancer? Also, is the partoid papilla on this side seems normal? And what does this flaky line type spots on where the pigmentation is? First pic is of left side, 2nd pic(zoomed one) is of right side. I got it checked by dentists and ent too, after clinical checkup, they're saying its normal but when i workout and get thirsty, that time roughness is more prominent and also sometimes during regular day hours too! Should I go for biopsy? If yes also m really really scared, as this has been going on since 2 mnths :(. I wanna cry badly
